Fiscal control will be exercised through the use of monthly comparisons between actual expenses incurred and corresponding line items in the budget. The study will comprise: a. Literature search for all available data concerning the BFLAVO test, such as, meteorological conditions and radiation measurements. Discussions with scientific and technical personnel invol-ved in the BRAVO test. 1291 90SY, . ric samples and teeth samples to determine concentrations to derive concentrations cf o;her radionuclides. b. ~~~ Diet and life style assessment. c. d. ~~g~i?!18Pu studies to provide irtformation for dose Computer simulation to determine the transport and deposition - of radioactive fallout following the BRAVO test. ‘-. 19f. Technical Progress in BY-3 (H 1978). Preliminary literature search and consultations with Dr. C.A. Sondhaus, University of California, has been completed. This has resulted in defining areas of uncertainty in information available and establishing the procedural steps that should be carried out towards elucidating the problem. All available data on external radiation measurements, radionuclide concentrations in soil, water, vegetation, animal and food items have been collated. ~~jstoric I analysis. samples collected from Rongelap and Utirik have been submitted for Pertinent meteorological information pertaining to the BRAVO test have been researched and the information provided to Lawrence Livermore Laboratory so that they can go ahead with the computer simulation of the transportation and deposition of fallout.

Final analysis of a recent diet acd life s~yle study will on completion ?rovide an internal and external exposure estimate. All the data so gathered will be used to generate a model(s) for arriving at the dose estimate in terms of exposure at time of fallout.
